Objective of the paper is to promote the proactive approach in tire maintenance for commercial vehicles and application of the Tire Pressure Monitoring System (TPMS). Researches have confirmed that the installation of TPMS on commercial vehicles is technically and economically justified, namely traffic safety and comfort of passengers would thus be significantly improved and operating costs would be decreased. Example of articulated city bus shows that the investment in the Tire Pressure Monitoring System would be recovered in the second year of operation. Source

Elements that makes the traffic system, environment, vehicles and human, also represents integral part of any resulting accident. In addition to numerous improvements of vehicles, expansions and improvement of road infrastructure, the number of accidents have been increasing. The main culprit, human, who, with the participation of 57% (when combined with other factors accounts for more than 90%) of accidents, is the weakest link in the chain. This work covered and explains numerous human factors at which we can affect. The new Law on Traffic safety was taken in consideration. Analysis of accidents in function of the drivers age was conducted. The goal of measures, which have been proposed for suppression and prevention, is declining and reducing negative trends. Source

In turbulent commerce which characterizes all its branches, quality represents one of the rare tools that for companies provide possibility for diversification and separation from (dis) loyal competition. Neither Lagermax AED nor market of logistic services represent an exception. Company - Lagermax AED, as a leader in Serbian market, has recognized world trends and started with implementation of international ISO standards in own business. The aim of this paper is to indicate to some issues that Lagermax has during the process of standard implementation, as well as all benefits that company has and will have in near future, which would come from generally accepted and confirmed management system.

In recent years, motor vehicles industry has shown a tendency of replacing electromechanical components by mechatronic systems with intelligent and autonomous properties. The integration of hardware components and implementation of advance control function characterize this replacement. In this paper, we have applied the system approach and system engineering methods in the initial phase of vehicle active suspension development. An emphasis has been placed upon the interrelations between computer-aided simulation and other elements of the development process. The benefits of application of active suspension simulation are numerous: reduction of time to market, the new and improved functions of mechatronic components/devices, as well as the increased system reliability. In suspension model development, we used CAD/CAE tools, as well as the multipurpose simulation programs. For simulation, we used the one-quarter vehicle model. The modelling was carried out through the state-space equation, after which we designed the controller for our system. During this, we considered only the digital systems of automatic regulation. ©2011 Journal of Mechanical Engineering. All rights reserved. Source

This paper shows the way FMEA method (Failure Modes and Effects Analysis), which is widely used in motor vehicles industry, can be improved and later used during certain stages of vehicle life cycle. This is illustrated by the example of bus superstructure development. A number of possibilities have been given for the advanced method application during the selection and performance of vehicle maintenance process. A great deal of attention has been paid to risk analysis and the implementation of this parameter into the FMEA method, at the same time insisting on the inconsistencies of the traditional method. The result of our efforts is a new and in our opinion, improved approach to vehicle failure analysis, which gives a new dimension to the entire process. It is evident that this problem is vital from the aspect of high cost of vehicle warranty as well. © 2010 Journal of Mechanical Engineering. All rights reserved. Source
